That’s what [Modest Maker] did and the resulting findings along with an attempt to beat the commercial system with some cheap capacitive sensors, are covered in a recent video that’s also ...

[James Eckert] got his hands on a Freescale MPR121 capacitive touch sensor. The chip in question speaks I2C and senses up to twelve simultaneous capacitive sense electrodes; break-out boards are ...

Capacitive sensing is used in many applications, including proximity, pressure, displacement, position, and acceleration sensors. Predicting the real-world performance of capacitive devices ...
